When you connect to a modem pool with the Small Business Server Modem Sharing service from a Windows 2000-based computer, the modem may not respond or may respond incorrectly by not dialing, dialing only in pulse mode, or without using other initialization strings.
An incompatibility between the standard Unimodem driver and the Modem Sharing client results in a corrupted modem initialization string being sent to the modem. This prevents the modem from responding correctly.
